Are you fed up with measly cash ISA rates? Well, you could try switching - or you could look for higher returns with a peer-to-peer lender.

Peer-to-peer lenders are online platforms connecting borrowers with lenders (that’s you). In return for lending some of your savings for five years, you can expect a rate of 5% or more. Popular peer-to-peer lenders include Zopa, Funding Circle and RateSetter.

But before you throw all your savings at a peer-to-peer lender, make sure you’ve chosen the right one for you. We asked a spokeswoman from consumer watchdog Which? to explain more:

1. Understand the risks

Investors are directly connected to someone who wants a loan. So the biggest risk is that a borrower will fail to repay. Borrowers are credit checked. But, generally speaking, the higher the potential returns, the higher the risk they might not repay.

2. Check fees

With most sites you pay an annual fee, either as a percentage of your total investment or the amount of interest earned. You’ll also be charged if you want to get your money out.

3. Remember tax

Peer-to-peer lenders don’t deduct tax from the interest you earn, so you’ll need to declare this in a self-assessment tax return. Good sites should send annual statements to help with this.

In future, you may be able to invest in peer-to-peer lenders through an ISA. But the details of this have yet to be announced.

4. Choose an established lender

Peer-to-peer lenders aren’t covered by the Financial Services Compensation Scheme (FSCS). This means you could struggle to get your money back if a site goes bust – and a couple of smaller sites have gone under in the past few years.
